Rangers manager Mark Warburton praised Dumbarton's efforts after the Ibrox side's 2-1 win on Saturday.
Part-time Dumbarton proved difficult to break down for Rangers as Warburton's side lacked their usual attacking threat as they targeted a seventh win from as many Ladbrokes Championship outings this season.
It was not until the 63rd minute that Martyn Waghorn broke the deadlock, 10 minutes before he added another from the spot after Gregor Buchanan was dismissed for a last-man foul on Kenny Miller.
Garry Fleming pulled a goal back for the hosts from the penalty spot in the dying minutes, but there was no stopping the Glasgow side from maintaining their perfect start to their new manager's tenure.
Warburton conceded that Dumbarton had given Rangers a tougher afternoon than he would have liked and he was relieved to come away with the win.
He said: "They were very well organised, we had to take a bit more care in the first half.
"But they worked in teams and worked very, very hard to stop us.
"It is a tough place to come, they are well organised and we were respectful of that and the threat they posed.
"We have got another win but it doesn't come easy.
"The message to the players is 'it doesn't come easy, you have to go and get it'."
Dumbarton manager Stevie Aitken admitted he could not have asked for much from his players and is adamant they coped well against the team he is convinced will win this season's Championship and secure promotion to Scotland's top flight.
"In terms of how far we have come in a short period of time, we only put the team together 12 weeks ago and they have competed with a team we all know is going to win the league," he said.
"They will probably have it wrapped up by February if we're honest.
"I can be really proud of the players. They did everything we asked of them, there are a few tired legs in there but I'm proud of every one of them."
The two complaints Aitken did have, however, concerned the two moments of slackness which led to the two Rangers goals.
Waghorn was allowed too much room for the opener, before the swerve on his 25-yard strike wrong-footed Sons goalkeeper Mark Brown.
Mark Docherty played a slack pass which led to the penalty for Waghorn's second.
"We were disappointed because Waghorn comes off too easy and turns on our back four, in the first half that didn't happen," said Aitken.
"The second one is just a bad mistake."
